The room has two dedicated circuits. I'm not exactly sure what all is on the circuit that the lights are on, but I do know that it is dedicated to the fish room. So there cant be that much on it. All four ballasts however are connected to one DC4 (Direct Connect 4). I REALLY believe there is a short in one of two wires and/or one of two bulbs. I WILL find it!
There is a small amount of splash on the reflectors but I wouldn't say anything out of the ordinary. I definitely don't think there is any corrosion in the end caps. A, I don't see any corrosion, and B, I have run 660's for years in closed hoods with the bare bones cheap cheap end caps from Home Depot and never had issues like this. This is very strange to me.
The ballasts are on the end of the rack. You can look back a few pages and see where they are mounted. There is NO splash on these.
melev... the Photoshop corrections make a HUGE difference. I've always had high aspirations of being a purist in my photography as well as my reefkeeping and not wanted to cut corners or edit my photos. However, I am beginning to realize that I will never get ANYTHING accomplished if I don't learn to cut some corners and take the easier route every once in a while.

I'll be heading over to your tutorial here shortly as well.
Rocketboy52....the "teeth" in the overflow is simply plastic egg crate (or light diffuser plastic) and is cut to fit smoothly in the "notch" that was cut in the glass. It is siliconed in place.
Here's a better pic.
If that doesnt help, Im sure you can find some good pictures if you search for other Aquarium Obsessed tanks.
My return pump is rated at 790 gph. So I'm "guessing" when I say I think I am getting between 650 and 700 gph through the overflow. Some of that water goes to the secondary sump and then back to the main sump. Some goes through the water change sump and the rest goes directly to the main sump. But no matter how you cut it, the sump flow through is whatever the pump is pumping. When I add the frag tank and fuge into the system, this will get a bit more complicated so I'll wait until then to explain that.

I know some people probably think this is not enough flow through but I have never understood the concept of having massive amounts of turnover through your sump. I find it to be a waste of energy and smaller pumps are a lot cheaper than larger ones.
The two display pumps are actually EcoTech VorTech Propeller pumps. I have them set to ramp up and down between 500 and 3000 gph. So at any given time, I have as much as 6700 gph in the display. I can probably live with this for a while but I will eventually add one more VorTech, but probably no more than 2 more, for a total of 4 VorTech pumps.
